Who can host my box?

I have a DELL PowerEdge 1600 server box, same form factor as the 1800 line, so no small beast. It’s currently turned off, which is a pity, but it’s too noisy for me to have at home.

Do you have or know of a place where it can get shelter, power and IP, cheaply? In or around Copenhagen, so I can get to it when I need to. It doesn’t have to be a “professional hosting” place, as long as it’s reasonably reliable.
